The salient pole means the poles of the magnet are projected towards the armature of the motor. Each pole of the motor is excited by its exciting coil. The copper rings shade the loops. The loops are known as the shading coil.

The poles of the motor are laminated. The lamination means multiple layers of material are used for making the poles. So, that the strength of the pole increases. The slot is constructed at some distance apart from the edge of the poles. The short-circuited copper coil is placed in this slot. The part which is covered with the copper ring is called the shaded part and which are not covered by the rings are called unshaded part.

Rotor — The shaded pole motor uses the squirrel cage rotor. The skew can be done for obtaining the better starting torque. The construction of the motor is very simple because it does not contain any commutator, brushes, collector rings, etc.

They are all artistically enhanced with visually stunning color, shadow and lighting effects. Many of them are also animated.

Industrial Power Systems Three-phase induction motor Single-phase induction motor Auto Selection of any Available Phase, in 3 Phase Supply System - The basic idea for the development of the project is to provide supply to the single phase load if any of the phases, out of the 3 phases misses.

The power and torque developed by the motor will be three times that of one phase. So these motors are used in fans, blowers, centrifugal pumps, washing machine, grinder, lathes, air conditioning fans, etc.

Capacitor Start IM and Capacitor Start Capacitor Run IM The working principle and construction of Capacitor start inductor motors and capacitor start capacitor run induction motors are almost the same. We already know that single phase induction motor is not self starting because the magnetic field produced is not rotating type.

In order to produce rotating magnetic field there must be some phase difference. In case of split phase induction motor we use resistance for creating phase difference but here we use capacitor for this purpose. We are familiar with this fact that the current flowing through the capacitor leads the voltage.

So, in capacitor start inductor motor and capacitor start capacitor run induction motor we are using two winding, the main winding and the starting winding. With starting winding we connect a capacitor so the current flowing in the capacitor i.

Now there occur large phase angle differences between these two currents which produce an resultant current, I and this will produce a rotating magnetic field. Since the torque produced by these motors depends upon the phase angle difference, which is almost 90 o.

So, these motors produce very high starting torque. They are available up to 6 KW. Stator has two windings — main and auxiliary winding. It has only one capacitor in series with starting winding. It has no starting switch. Advantages and Applications No centrifugal switch is needed. It has higher efficiency and pull out torque. It finds applications in fans and blowers in heaters and air conditioners. It is also used to drive office machinery.

Shaded Pole Single Phase Induction Motors The stator of the shaded pole single phase induction motor has salient or projected poles. These poles are shaded by copper band or ring which is inductive in nature. The poles are divided into two unequal halves. The smaller portion carries the copper band and is called as shaded portion of the pole.

When a single phase supply is given to the stator of shaded pole induction motor an alternating flux is produced. This change of flux induces emf in the shaded coil.
